IPC: G10L19/018
Filed: 2003-07-07
Abstract: A watermark detection method is disclosed which is based on computing the cross-correlation between a suspect signal and a watermark. In order to be more robust against prolonged dominant signal components that adversely affect the correlation, the sequence of signal samples ( 61 ) to be correlated with the watermark is divided into sub-sequences (A(k)). The sub-sequences are processed, by a weighting function, to obtain modified sub-sequences (B(k)) that individually exhibit the original signal variations, but collectively ( 62 ) exhibit a flatter distribution of sample values. Dominant peaks in the signal are thereby substantially reduced.

Abstract: <P>PROBLEM TO BE SOLVED: To prevent the occurrence of shocks due to a sudden change in an engine brake and the restart of fuel supply in the state where the engine rotation speed is below the F/C return rotation speed to impair the fuel consumption.  <P>SOLUTION: The downshift gear change speed at the time of coast is configured to be large when the degree of speed reduction of a vehicle is large, i.e., brake is ON. Thus, when the degree of speed reduction is large, down shifting is carried out quickly, and the time necessary for the engine rotation speed NE to reach the F/C return rotation speed NEFC to restart fuel supply becomes longer to improve the fuel consumption. Since the downshift gear change speed is slow when the brake is OFF and the degree of speed reduction in the vehicle is small, changes in engine rotation speed NE and engine brake are moderate to inhibit gear change shocks.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
